@HotSpotIntrinsicCandidate is accessible in java.base where the usages 
are. It's visible (you can see it) but isn't accessible outside of the 
java.base. So I expect you should be able to invoke annotationType() to 
get the annotation type, you just won't be able to do much with it.

The export of  package "jdk" is temporary, it's due to @jdk.Exported. 
JEP 261 proposes to remove this, it just hasn't been done yet.
